gen x replied to the thread Undergrad Reference frames, center of rotation, etc.How can rotation about points A, B and C be the same, acelometer placed on Earth will read different values? Rotation for points B and...

gen x replied to the thread Undergrad Reference frames, center of rotation, etc.Why is force frame dependent? If acceleration is the same, and m is the same then why F is not equal? ..F=ma

gen x replied to the thread Undergrad Reference frames, center of rotation, etc.vl(t) =ω⋅l vl(t)=v
-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.I thought maybe " r" of local curvature in specific point. Doesn’t the centripetal force have to be the same in both reference frames?
-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.math: Cf=m x 0^2 /r = 0 Yes that is good question. point t1 has centripetal force to the right toward center for frame fixed to center...

gen x replied to the thread Undergrad Reference frames, center of rotation, etc.In answer are some parts that you(members in my thread) claim are wrong. I will qoute them: "To make the point of rotation the center...

gen x replied to the thread Undergrad Reference frames, center of rotation, etc.How can I move object from postion 2 in position 1, with pure rotation if I don't use center of this circle?

-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.There is only one center for this rotation that is substitution for rotatio+translation?
-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.If I choose one point as center then everything else rotate around that center Do you suggest any video lecture about my topic?
-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.If we choose center as B, B is now fixed and everything rotate around B, so how CoM still move in stright line in this anylize?
-
gen x replied to the thread Undergrad Reference frames, center of rotation, etc.Because Dale said that B will not move in straight line, so everything what moves in curve need centripetal
